The Killing (season 3)

Season 3 begins one year after the close of the “Rosie Larsen” case (the focus of the series’ first two seasons) with Sarah Linden no longer working as a detective. But when her ex-partner Stephen Holder’s search for a runaway girl leads him to discover a gruesome string of murders that connects to a previous murder investigation by Linden, she is drawn back into the life she thought she’d left behind.
